Powerline Carrier-powerlink

Model: powerlink

PowerLink uses the high-voltage line between transformer substations as a communications path for data, protection signals and voice.


The SWT 3000 Teleprotection system is the highly developed solution world wide for identifying and isolating faults extremely quickly in the high-voltage grid. Combined with existing distance protection relays, it allows operators to reduce downtime to an absolute minimum. The current stage of development is based on 50 years of practical experience and adaptation to changing challenges.

The SWT 3000 protection signaling system is extremely versatile. For example, it can use analog and digital networks as communications infrastructure. At the same time, it’s ideal for establishing substation-to-substation communication via IEC 61850.

PowerLink 50
The PowerLink 50 is a smart and compact power line carrier single-frame system with up to 50 W transmission

PowerLink 100
The double-frame system offers full flexibility concerning transmission power (20 W – 100 W) and modular expandability.


  • Cost-effective for small to medium data volumes overlong distances
  • Use of utility-owned resources (power lines)
  • Highest reliability (for example, for protection signaling)
  • Can be used in effective combination with broadband technologies for highest availability
